Performance Evaluation of a Low-cost Cold Storage System on Fruits and Vegetables in Rural Areas
No full textThis paper evaluates the performance of a low-cost cold storage system developed to preserve the quality and extend the shelf life of perishable agricultural produce, including fruits and vegetables. The low-cost cold storage system was constructed using locally available materials and energy-efficient components, the system aims to offer an affordable and accessible solution for small and medium-scale farmers in the rural areas of Nigeria. Internal temperature control and stability, the performance parameter was assessed under varying load conditions using selected produce. The system effectively maintained optimal storage conditions, significantly reducing post-harvest losses and maintaining the freshness of fruits and vegetables over an extended period compared to ambient storage. This is particularly critical in regions within the Inter-tropical Convergence Zone, where high ambient temperatures contribute heavily to postharvest losses, threatening food security and sustainability. The smart cold storage unit, designed with a capacity of 20kg and a temperature range of -17°C to 55°C, stored fruits (mango and pineapple) at 9°C and vegetables (cabbage and carrot) at 0°C, while control samples were left at ambient temperatures ranging from 31.4°C to 35.2°C. After 5 hours, produce stored in the system exhibited significantly lower weight loss: mango (0.7% vs. 1.9%), pineapple (0.75% vs. 2.75%), cabbage (1% vs. 3.5%), and carrot (2.1% vs. 7.6%). These results demonstrate the system\u27s effectiveness in reducing deterioration caused by high temperatures, slowing respiration rates, and extending shelf life. The cold storage unit\u27s consistent performance and minimal energy consumption make it ideal for rural or off-grid use, especially when powered by renewable energy. Overall, this study underscores the potential of smart, low-cost cold storage technologies as sustainable solutions for reducing food waste and enhancing food security in temperature-sensitive regions
Structural Performance of Reused GFRP Bars in Reinforced Concrete Beams: A Sustainable Approach to Concrete Reinforcement
No full textConstruction demolition waste is a growing environmental concern in developing countries like Ghana due to rapid urban expansion. Glass Fiber Reinforced Polymer (GFRP) bars, known for their high tensile strength, full linear-elastic response, corrosion resistance, non-conductive and lightweight nature, offer a sustainable alternative to steel reinforcement. However, their disposal remains challenging due to their non-biodegradable nature. Reusing and recycling GFRP bars present a viable solution, minimizing waste and reducing the construction sector’s carbon footprint. This research focused on reused GFRP bars recovered from previously tested beams that failed due to concrete crushing, based on concrete controlled sections, while leaving the GFRP bars intact. The mechanical properties of the reused GFRP bars were evaluated to provide holistic data for this study. Five beam specimens with varying concrete strengths (23.1 N/mm², 15.6 N/mm², 16.90 N/mm², 16.02 N/mm², and 22.86 N/mm²) were reinforced with 12 mm reused GFRP bars at tensile reinforcement ratios of 0.71%, 0.94%, 0.86%, 2.11%, and 2.11%, combined with a fixed steel shear reinforcement (8 mm bars at 200 mm stirrup spacing) aimed at hybrid reinforcement respectively. These beams were subjected to four-point monotonic loading to assess their structural performance. Key parameters examined included ultimate flexural strength, deflection, cracking mode and failure mode. Experimental results revealed that the reused GFRP bars had retained their characteristic linear-elastic stress-strain behavior and high tensile strength without notable loss in mechanical performance. All reused GFRP-reinforced concrete beams exhibited linear-elastic behavior up to failure, with average experimental failure loads exceeding theoretical predictions by a factor of 1.47. Failure modes included diagonal tension failure and concrete crushing was predicted by theoretical analysis. Increasing the concrete compressive strength and tensile reinforcement ratio of reused GFRP bars improved structural behavior under bending loads, attributed to the high tensile capacity, improved stiffness, and bonding properties of the bars, similar to the findings observed in the virgin GFRP RC beams in their maiden form. These results highlight the superior durability and reusability of GFRP bars and their potential to enhance the sustainability of reinforced concrete structures, marking a significant step toward the practical reuse of composite materials in construction
